First multiple both sides by 4 = 12k^2+29k-1000, rewrite it 12k^2+125k-96k-1000=0, factor k out from the expression k x (12k+125)-96k-1000=0, then factor out 8 k x (12k+125)-8(12k+125)=0, factor out 12k+125 to (12k+125)x(k-8)=0, now when the product of factors equals 0, at least one factor is 0 - 12k+125=0 k-8=0, solve the equation for k k=-125/12

k=8

Find the measure of angle c

Vlad [161]

Answer:

Roughly 70.29 degrees

Step-by-step explanation:

Equation:

(2x+27)+(2x-11)+3x = 180

7x + 16 = 180

7x = 164

x ~ 23.43

Angle C:

3x

Answer:

c = 29

Step-by-step explanation:

Law of sines is given as: $\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}$

B = 180 - (57 + 44) = 79°

b = 41

C = 44°

c = ?

Thus:

$\frac{b}{sin(B)} = \frac{c}{sin(C)}$

Substitute

$\frac{41}{sin(79)} = \frac{c}{sin(44)}$

Multiply both sides by sin 44

$\frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44)$

$\frac{41*sin(44)}{sin(79)}*sin(44) = c$

c = 29.0140633 ≈ 29
